MAGAZINE-HAMMER.

Application filed December 29, 1919.

To all whom it may concern:

Be it known that I, CLARENCE J. Porn, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Magazine Hammers, of which the following is a specification.

My invention relates to new and useful improvements in magazine hammers, and has for its object the provision of a magazine hammer which will be durable in structure, economic of manufacture, and highly efficient in use.

from the inner surface thereof. The members 13 are provided adjacent their inner ends with an enlarged portion 14:, at each side of which is formed a longitudinally extending groove 15. Projecting inwardly from the cap 10 is a tubular member 11, which serves as a bearing in which one end of the shaft 36 is ournaled. Mounted upon the opposite end of the member 11 is a cupshaped housing 17, in which the driving elements and cooperating mechanism are mounted. The driving end of the hammer is divided into two parts, one portion 18 which is mounted upon one end of the magazine 11 and the other portion 19 which is rigidly secured to the housing or casing 17 by any suitable means, preferably by having the member 17 contracted tightly upon it. The member 18 is provided with a recess in which the end of the member 11 seats. Positioned upon the member 11 at the end to which the housing 17 is secured is a gland or am nut 22, which is eXteriorly threaded and adapted to thread into the recess 21 formed in the member 18. Slidably mounted within the housing 17 is a weight 23 which is secured to a driving member 24 which serves to drive the tacks or nails used with the device. The member 24 is connected to the member 23 by means of a bolt 25 threaded into a socket formed in the member 24 and into a socket formed in the member 23. A member 25 is provided with a nut. 26 by means of which the member 25 may be threaded into the sockets formed into the members 23and 24, thereby adjusting the relative distance between these two members, the opposite ends of the member 25 being oppositely threaded. Positioned within the housing 17, are spiral springs 27, one end of which is adapted to engage against the lower surface of the member 23, and the opposite end against the upper surface against the member 18, or 19, depending upon which side of the member 25 the springs are positioned. Projecting from one side of the member 23 is a lug 28. Slidably mounted in the lug 28'is a rod 29, the lower end of which is pivotally connected to a pawl 30, which is adapted to engage at its-lower end with ratchet teeth 31 arranged upon a drum 82, which is rigidly mounted upon the member 11. Mounted upon the member 17, adjacent its lower end is a guide lug 33, through which the/member 29 is projected. Mounted adjacent the upper end of the member 29 is a collar 34, having a set screw 3 1 by means of which the member 3a may be adjusted on the rod 29 and secured in its positions of adjustment. Positioned upon the rod 29 intermediate the members 31 and s3 and contacting with the members 33 and 31 at its opposite ends is a spiral spring 35.

Projecting inwardly from the member 18 is a tubular member in which is journaled one end of the shaft 36. its clearly seen in Fig. 1 and Fig. 5, the shaft 36 is provided with a worm thread. Mounted upon the shaft 36 is a drum or hub 37, radiating from which are spokes or arms 38, so as to form a star wheel. As clearly seen in Fig. 8, the members 38 each project into one or the compartments 12, in which the magazine is divided, the members 13 being spaced apart at their inner ends sufficiently to allow for the passage of the members 38 therein. hilounted upon each of the members 38 is a spiral spring 39 which carries a washer or shoe 39 at its free end which is adapted to abut against the nails or tacks tO which are used with the device.

In operation, the nails or tacks which are intended to be used with the device are inserted in a card board 453 at certain predetermined intervals. The card boards are then inserted into the compartments 12, so that the heads of the tacks or nails engage in the grooves 15. In order to insert the strips of card board or paper which l'iear the nails or tacks, the cap 10 is removed. After the strips bearii'ig the nails or tacks are inserted into the compartments 12, the star wheel is placed upon the shaft 36 and the shoe or plate 39 on each arm or spoke abuts against the end tack or nail in its respective compartment and tends to force the same outwardly through the forward or driving end of the device. In order to al low for the passage of the tack or nail outwardly through the member 18 so that the tack or nail will be positioned in the space 20, which separates the members 18 and 19, a slot 11 is provided. Upon striking the ends of the members 18 and 19 against an object, the member 23 is carried downwardly by its momentum against the tension of the springs 27, thereby forcing, by means of the member 2%, the tack which is positioned in its path downwardly and driving the same into the object upon which the members 18 or 19 have struck. As the member 21 moves downwardly with great rapidity, the paper or card board 13 will be cut oil and carried downwardly with the driven tack. The device is so constructed that at the same time the paper. strip is severed by means of the member 24, the pawl 30 engages with the teeth 31 and causes the compartment 11 to rotate, thereby bringing the next compartment into alinement with the slot 11, so that upon the member 2-1 resuming its normal position in response to the tension of the springs 27, the tack or nail will be forced from the compartment which is alined with the slot d1. Inasmuch as the shaft 36 is stationary, the star wheel will be caused to rotate upon the shaft 86, as the magazine 11 rotates. The worm thread upon the shaft 86 is so constructed that the star wheel moves upon the shaft 36, during one rotation of the magazine, a distance equal to the distance between any two of the tacks or nails used in the device, so that the same pressure is. always exerted upon the tacks for feeding the same forward. Upon the rebound of the members 21- and 23, the pawl 30 rides over the teeth 31 so tha the magazine is not rotated when the driving elements are moving to their normal position.

In the form shown in Fig. 1, I have provided the member 23 with a laterally X- tending portion aid, which constitutes a rack bar, the same being provided with teeth It is also .to be noted that the member 2 1 is formed integral with the member 23, and nomeans of adjustment is afforded. Mountedupon a shattwhich is rigidly mounted in the housing 17 is a gear wheel 4C6, which is provided with teeth 48 adapted to mesh with the teeth 15, upon the downward movement of the member23. As clearly seen in Fig. 3, the gear wheel 46 is formed in the shape of a drum and provided on its inner surface with ratchet teeth 41S). lligidly mounted upon the shaft 17 is a collar 50 projecting from oneside of which is a lug 5.1., to which is pivotally mounted a pawl 52, normally held in engagement with the teeth 19 by means of a spiral spring 53, which abuts against a post 5% mounted upon the member 50. The wheel dfiis loosely mounted upon the sh aft 17. Rigidlymounted upon the shaft 47 is a gear wheel 5-1: which meshes with a gear wheel 55, which is rigidly mounted-upon the shaft 56. Suitable bearings 57 for the shaft 5.6 are mounted upon the housing Mounted upon the lower end of the shaft 56 is a bevel 58 which is adapted to mesh with a bevel gear 59, which is rigidly mounted upon a shaft 59. Rigidly mounted upon the shaft 59 is a drum 60 on the periphery of which is formed gear teeth .60, which are adapted to mesh with teeth 61 formed n 3011 a collar 62, which is rigidly mounted upon the magazine 11;

In operation, the .member 23 is moved downwardly through its momentum, as al ready described,.and causes the teeth 45 to come into mesh with the teeth -18 simultaneously with the -separation ofa tack or nail or the st'ripin which it is positioned. The

wheel 46 is thereby caused to rotate, causing the member 50 to rotate, owing to the engagement of the pawl 52 with the teeth 49. The shaft 56 is thereby rotated through the medium of the bevel gear 55, the bevel gear 54 thereby causing the drum 60 to rotate through the medium of the bevel gear 58 and the bevel gear 59. In this manner, the magazine 11 is rotated through the meshing of the teeth 61 with the teeth 60. A similar slot 41 is provided for the passage of the tacks or nails there-through so as to be positioned in the path of the member 24. The operation of the feeding mechanism is theLsame as al ready described, but it is to be noted, as clearly seen in Fig. 4, that the number of compartments is increased, thereby increasing the capacity of the hammer. It is also to be noted that in the form shown in Fig. 1, the tacks are fed from the top of the magazine, whereas in the form shown in Fig. 5, the tacks are fed from the bottom of the magazine.

My magazine hammer. is designed primarily for use in tacking up posters and the like where the presence of a strip of paper between the head of the tack and the object nailed or tacked is of little concern. By the use of a hammer such as I have described,

the hammer described may be loaded or filled with tacks and used for a considerable length of time without further concern for the tacks. Such a hammer is also useful where the object to be tacked is above the reach of the person and eliminates the necessity of using a magnetized hammer such as is now customarily done.

lVhile I have illustrated and described the preferred form of construction for carry ing my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
